An Austro-Keynesian?

Posted on the 21 September 2012 by Lachmannian @TheLachmannian

I received an e-mail a couple days ago, which I will reproduce some of it here. It is part of an email conversation I have been having for a while now with a PhD student that thinks of himself/herself as an Austrian. He/She has requested to remain anonymous:

Isaac, I have come to the conclusion that you are the combination of Austrian and Keynesian thought. You’ve said before that you approve of Keynesian stimulus in slumps, you question the validity of Say’s law, you don’t agree with loanable funds theory, etc. And your justifications for not believing in these primarily come from Keynesian resources. Nevertheless, you still defend the basic core of Austrian economics, which deals with the emphasis of human action. To a certain extent, you agree with praxeology, you claim that economic theory as a whole must be described through acknowledging the actions of people. In other words, “microfoundations play a key role” as you have stated before in our email conversation…

Your radical subjectivist idol seems to be [Ludwig] Lachmann, and you assume that everything you approve of, Lachmann would too, but I dont think this is quite right. If anything, you are more of the Shackleian radical subjectivist, who is seen as a person who uses ‘austrian’ premises to keynesian conclusions. In other words, you are setting up to be the modern day Austro-Keynesian.

I think the PhD student has some fair points. I do agree that I partially assume that Lachmann would approve what I advocate. I would state this differently though, rather, I assume to be consistent with a Lachmannian framework to where I draw my conclusions. For example, my advocacy of endogenous money did not really come from reading Keynesian resources, it came from reading Lachmann’s (1937) “Uncertainty and Liquidity Preferences,” in which the article considers money’s function as one that has ‘debt discharging’ which is the main difference of money and a commodity in modern capitalistic systems (Lachmann 1937: 305). Lachmann also goes on to say that money is also legal tender and can explain the process through logical deduction by making the reader aware of “what money does and what only money can do” (Lachmann 1937: 307). Lachmann seems to be the only Austrian to endorse this claim on money, thus when I do try to justify endogenous money and legal tender, I have to by default use Keynesian articles, for they have expanded this concept, while the modern Austrians still hold on to a commodity-money relationship, who oppose legal tender laws. So yes, while I use Keynesian articles to justify my point, I still think it is consistent with the Lachmannian framework.

Another key article of Lachmann’s (2005) article “Speculative Markets and Economic Complexity,” in which it shows the instability that capitalistic market systems has. He urges to make the distinction between ‘ordinary markets’ (which is a generalized form of the typical supply-demand market analysis, ie. the discovery process) and financial markets (specifically speculative markets), which are different since expectations seems to make this market more acceptable to instability (Lachmann 2005: 264; 267). Indeed talking about speculation and financial markets makes stability theories like Say’s Law and loanable funds questionable. Certainty, (Post) Keynesians see it this way and have furthered the literature on it, which Austrians have not really done so, since they faithfully hold onto the loanable funds theory, probably in fear that if they reject loanable funds, their Austrian Business Cycle (ABCT)  is also worth throwing out

I admit that Lachmann was not too clear on his thoughts on the Austrian Business cycle. It is generally known though that he thought the theory lacked a role of expectations and, according to Lewin in one of our email conversations, it was “too mechanical.” Also with conversation with Lewin, we discussed whether Lachmann would approve of the loanable funds theory, Lewin said he probably would have while I took the opposing view. But after our online talk, I realized if Lachmann himself did not agree with me of his position (assuming that he supported loanable funds theory of course. As Lewin said at the end of the discussion, this is something that we will never know), who cares? I am only concerned with using the Lachmannian framework and expanding on it. So a better discussion would have been if my positions are consistent with the Lachmannian framework. In order to conclude from my interpretation of the Lachmannian framework that ABCT is questionable, I must show a connection how the lack of expectations might lead to at least being skeptical of the ABCT (and at most, completely rejecting it). And I could do this very easily by pointing to Lachmann’s (2005) article “John Maynard Keynes: A view from the Austrian Window” in which he makes that controversial statement that Keynes was more committed to subjectivism that the Austrians (Lachmann 2005: 187)! Keynes’s psychological law to his view of expectations (thus making markets instable) all contribute to Keynes as a subjectivist. But the simple fact of expectations making markets unstable is something that the ABCT lacks due to its appeal on loanable funds (Ertürk 2006). Also, it not like the Austrians haven’t heard of this reasoning, they just refuse to accept it. I would look at the G. Hill (1996a; 1996b; 1998) and the S. Horwitz (1996; 1998) debate for an example.

So am I am Austro-Keynesian, I don’t know, I guess it depends how one defines it. I obviously have a lot of Austrian influence and a lot of Keynesian influence, but it is all consistent to the Lachmannian framework, which is the radical subjectivist Austrian view. Instead of creating new labels like Austro-Keynesian, I would just much rather be label a radical subjectivist.
